Abstract

The invention relates to a continuous-flow machine (210) for a fuel cell system (205) with a fuel cell stack (206) for a vehicle (200a), in particular a utility vehicle (200b), wherein the continuous-flow machine (210) is designed to apply an air flow (240) to the cathode side of the fuel cell stack (206); wherein the continuous-flow machine (210) has an electric drive (215) and at least one compressor wheel (216), which can be driven by the electric drive (215) and is rotationally fixed to a rotor shaft (214), for drawing in supply air (239) and for providing the air flow (240); the continuous-flow machine (210) has a bearing assembly (217) for mounting the rotor shaft (214); and the continuous-flow machine (210) has at least one fluid-guiding lip (220); wherein the fluid-guiding lip (220) is designed to guide fluid (90) within the continuous-flow machine (210) around the bearing assembly (217) and / or to block a transporting of the fluid (90) in the direction of the bearing assembly (217).
